I see this too, this is not terminal related. It happens in all terminals and
even the CTRL+U pgup keybinding doesn't work.
Downgrading to 3.2 from FC-5 unsurprisingly fixes this. BTW I'm on x86_64, are
the others who have this on 64 bit too?

Since this is anoying the hell out of me I've taken a look. The problem is that
patch4 has been merged upstream but still gets applied (with a lot of fuzzy
matching I guess) to the upgup function in uedit.c, where it was never supposed
to be applied.
Removing: "Patch4: joe-3.1-ret.patch" and the belong %patch line fixes this.
